Tips Auto Calibration Function for CO2 Sensor

What is “Auto Calibration” ?
Auto calibration is a function designed to enable long term accurate measurements for the TR-76Ui by gradually adjusting the lowest measured CO2 concentration over a 180 hour period, to the global average concentration (atmospheric CO2 level of 390 ppm).

• The factory default setting for auto calibration is ON.

Turning ON and OFF Auto Calibration

Turn off auto calibration (1) when continuously measuring in an environment where the lowest CO2 concentration differs greatly from the global average concentration of 390 ppm.
In this case, to ensure accurate measurement results, periodically place the TR-76Ui in fresh air outside and check if the measured CO2 concentration values are close to 390 ppm or not. If not, we recommend that you carry out manual calibration (2).

1. The factory default setting for auto calibration is enabled. To change this setting, go to the
   [Settings] menu and select [Auto Calibration Settings].

2. The measurement of the CO2 sensor may have a slow drift. It is recommended to perform manual calibration about once a month. For details about manual calibration, please refer to
   [TR-76Ui Operation Guide]- [Available Settings] .

1. Make sure to use the data logger within the operating environment as listed in the specifications.
2. When continually used in environments with temperatures above 60°C, accuracy of humidity measurements will decrease over time. Also, humidity cannot be measured at temperatures below -20°C.
3. Stated value is the measurement accuracy of the CO2 sensor when Auto Calibration is operating properly. A change in atmospheric pressure directly influences the reading of CO2, which can cause measurement errors; a decrease in pressure by 10 hPa results in a relative decrease in CO2 by 1.6%. In such a case, we recommend carrying out the “Atmospheric Pressure Correction” function found in CO2 Recorder for Windows.
4. If you wish to use infrared communication to download recorded data, it is necessary to purchase the Data Collector TR- 57DCi (sold separately).
5. Customers wishing to write their own software, please contact your local distributor for the serial communications protocol specifications. (Note: Optional serial communication cable TR-07C is also required.)
6. In order to use the external alarm terminal, please purchase the optional alarm connection cable (AC0101)
7. Battery life varies depending upon the ambient temperature in which it is used, the recording interval, the frequency of communication, and the battery performance. All estimates are based on operations carried out with a new battery and are in no way a guarantee of actual battery life. Battery life may be shortened if the unit is used under inverter type fluorescent lighting.
8. For installation, it is necessary to have Administrator (Computer Administrator) rights.
9. We recommend using an operating system in the same language as the display language. Operation in different languages is not guaranteed.
   The specifications listed above are subject to change without notice.

Cautions about using the Temperature-Humidity Sensors

• If extremely severe temperature changes occur, the humidity measurements may appear abnormal. Once the sensor’s temperature becomes stable, the measurements will return to normal.
• Do not connect the sensor to any data logger other than those specified by T&D Corporation.
• Do not expose the sensor to a strong impact. This may adversely affect measurement accuracy and cause damage or malfunction.
• When the sensor is not to be used for a long period of time, please store it at normal temperature and humidity.
• Do not allow the sensor to become wet. If the sensor gets wet, immediately remove it from the unit.
• Do not use the sensor on the human body.
• Do not expose to condensation, dampness, corrosive gases, or organic solvents.
• Continued use may cause a decrease in the sensor’s accuracy and sensitivity even under normal operational conditions. If the sensor is being used in a bad environment (smoky or dusty places) it may be necessary to change the sensor sooner.
• The SHA-3151 is not water resistant. If the sensor gets wet, immediately remove the sensor from the unit and wipe it with a clean cloth as soon as possible. Then allow the sensor to dry in normal room temperature before using it again.
• When using the THA-3001/3151 in an environment where the humidity is under 30%RH, the measurements may sometimes fluctuate. This is not abnormal.
